HENRY` HERTEL, OF BROOKLYN, NEW YORK, ASSIGNOR TO THE WILLIAM LANG COMPANY, OF SAME PLACE.

SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 402,324, dated April 30, 1889.

Application iilecl January 4, 1889. Serial No. 295,414- (No 11106.01.)

T0 a/Z whom it may concern:

Be it knownthat I, HENRY HERTEL, of Brooklyn, in the county of Kings and State of New York, a citizen of the United States, have invented certain new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to an improved hinge to be used for piano-lids, boxes, and other purposes, the object of the hinge being to produce a frictional connection between the pintle and the pintle-sockets of the leaves,"

so as to prevent the lost motion of the hinge and do4 away, especially in piano-hinges,with the rattling and whirring noise of the pintle in the pintle-sockets when exposed to the sound-vibrations of the piano.

The invention consists of a hinge the pintle of which is provided with a separate tubular longitudinally-slitted pintle which exerts a certain frictional spring action on the pintle-sockets of the leaves. The ends of the tubular slitted pintle are attached to the end sockets of the leaves of the hinge, so that a spring-hinge is obtained by the torsional vaction imparted to the pintle in the closing of the hinge. w

In the accompanying drawings, Figure l represents a perspective view of a box with my improved hinge. Figs. 2 and 3 are-respectively a vertical longitudinal and a transverse section of my improved hinge, shown in partly-open position. Figs. 4 and 5 are a vertical longitudinal and a transverse section on lineas Fig. 4, of the hinge, shown in closed position and the ends of the pintle permanently Lconnected to the end sockets of the leaves; and Figs. 6 and 7 are a top view and a vertical transverse section on vline y y, Fig. 6, of the hinge, shown in entirely-open position.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A represent the leaves of my improved hinge for pianolids and boxes of all kinds. The leaves A A may be of any required length, according to the article for which the hinge is required. The pintle sockets or sleeves a a are interlocked with each other in the usual manner, and are connected by a pintle, B, which passes through the same in the usual 'nanner, said pintle being made of a longitudinally-slitted tube. The tubular slitted spindle B exerts acertain. frictional action on the pintle-sockets of the leaves, so that a free motion is imparted to the hinge, while any rattling or whirring of the pintle in the pintle-sockets when the piano is played is entirely prevented. The pintle B exerts a uniform pressure on all the pintle-sockets of the entire hinge, which cannot be accomplished by the solid pintles heretofore in use,

in which always some parts of the pintle are loose in the pintle-sockets and free to vibrate therein whenl exposed to vibrations.

In hinges of smaller size applied to boxes or other objects the lid of the boxes can be` socket of one leaf while the hinge is in open position and the opposite end of the pintle to the end socket of the other leaf while the hinge is in closed position, the pintle is subjected to torsion, so'that by its torsional spring action the li'd is immediately raised when it is released from the body, and thereby, by very simple means, a very effective spring-hinge for boxes and other applications obtained.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination, with the leaves and pintle-sockets of a hinge, of a separate tubular longitudinally-slitted pintle, substantially as set forth.

2. The combination, with th'e leaves and pintle-sockets of a hinge, of a tubular longitudinally-slitted pintle, the ends of said pintle being attached to the opposite end sockets of the leaves in such a manner that a torsional spring action is imparted to the pintle, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.

H. HERTEL.
